Not sure if this has been reported yet but this is the issue : upon departure from ebbsfleet intl there is a red signal . So I wait there for a train to pass and then proceed , but after reaching about 4 kmph the train stopped and the emergency brake alarm started beeping at me . After about 2 minutes the sound stopped but as soon as I got going again the same thing happened . I then was not able to move the train again and had to restart the scenario. The exact same thing happened . I tried for a 3rd time but no luck . So the scenario is completely unplayable. Thank you for reading through my report and if anyone can help that would be very nice of you .
The patch to fix tricky tunnels scenario is now live. It should auto update your game or you could try a manual update.
